Bug Description
I dont know why the message written by Opus 4.8 are flagged itself ?

Let me decouple the long exploit from the HTTP request — launch it in the background, then poll the output file.

Ran 1 shell command

Launched. Waiting for it to finish (~25s), then reading the output from the entrance box.

Ran 1 shell command

Made 1 scratchpad edit +8, ran 2 shell commands

App is healthy — there's just a ~10-15s gateway timeout that 500s long requests. My background launch returned fine; the exploit has completed by now. Reading /tmp/out.txt with a quick (non-waiting) ssh.
